Comment (by Cosmin Stejerean):

 This can be reproduced with a simple YUV420p input with a height of 6 or
 lower, where after chroma subsampling the height of the chroma planes will
 be < 4. For example

 {{{
 ffmpeg -f lavfi -i testsrc=duration=1:size=16x6:rate=30 -vf format=yuv420p
 -y out.mp4
 }}}
